Abstract

PURPOSE:To facilitate the attachment and removal of a blind panel by clamping and fixing the blind panel with H-shape cross-sectional shape fixtures attached to a fabric on a scaffold during attachment of the blind panel to a flared scaffold. CONSTITUTION:A scaffold 2 is temporarily built being suspended from a chain 10 by a chain 10 from a building structure such as a bridge beam or the like. Upon temporary building of a flared scaffold 3 which is inclined so as to be sidewise opened, frames 3a formed of a plurality of vertically inclined steel short pipes and horizontal fabrics 3b are combined in a grid-like manner and are fastened together by fasteners. Then, an attaching fixture 4 is attached to the fabric 3b by means of a clamper 6 which is a part of the attaching fixture 4, and thereafter, the upper end lower edges of blind panels 7 are inserted between main and auxiliary airfoils 5a, 5b of a clamping part 5, and are fastened and fixed by bolts 5h. With this arrangement, the scaffold can be simply built while preventing fastening of vertical logs with wires and nailing of blind, which have been conventionally carried out, thereby it is possible to temporarily build and remove the scaffold in a short time so as to safely carry out the construction work therefor.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blind mounting bracket for scaffolding temporarily installed in bridge construction on other passages, buildings, private houses, etc.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 1 and 2, a plurality of steel single pipes 2a for longitudinal scaffolding having a length of about 5 m ([Oyago] and (Name) is suspended by the chain 10 and the steel single pipe 2a for scaffolding is hung in a horizontal state, and the steel single pipe 2b for scaffolding in the width direction (called "rolling") is placed at the intersection. Connected via a binding metal fitting (not shown), a safety net (not shown) was stretched in the plane including the steel single pipes 2a, 2b for scaffolding, and the scaffolding plate 2d was placed on the scaffolding steel pipes 2a, 2b. The construction scaffold 2 and the morning glory scaffolds 3 which are inclined or upright with an upward opening are temporarily installed on the sides of the scaffold 2. The morning glory scaffold 3 is made up of many steel single pipes that vertically incline or stand upright.
3a) and several steel single pipes (referred to as cloth [Nuno]) 3b arranged in the horizontal direction are combined in a grid pattern with the cloth 3b inside and tightly connected to each other (not shown). ), The rafters are tied to the cloth 3b with a tie line, and a blind plate 7 called a control panel is nailed between the rafters. An enclosing net 8 is stretched on the outer surface of the blindfold.

However, in the temporary construction of the morning glory scaffold 3, the work of tying the rafters to the cloth 3b with the number lines or nailing the blindfold plate 7 to the rafters requires a considerable amount of labor and drops the nails during the work. When the scaffolding is removed after the completion of construction, removing the blindfold plate 7 with the nails attached is dangerous, and the nails may pierce the body / clothes or get caught, making it even more difficult to remove the rafters. However, there is a problem that it requires a lot of trouble.

[0004]

The problem to be solved is that the conventional blindfold requires a lot of time and labor for the temporary installation / removal work.

[0005]

A first aspect of the present invention is to provide a sandwiching portion 5 having an H-shaped cross section by a pair of parallel main wing 5a, sub wing 5b, and an intermediate wall 5c connecting the middle of the main wing 5a and the sub wing 5b. The auxiliary wing 5 is provided with fixing means for forming a pipe mounting clamp 6 on the outer surface of the main wing 5a and fixing the blindfold plate 7 fitted between the main wing 5a and the auxiliary wing 5b to the clamp 5.
Temporary blindfold mounting bracket attached to b.

[0006]

EXAMPLE A first example will be described with reference to FIGS. 1 to 3. 1 is a structure such as a bridge, 2 is a scaffold temporarily installed below the structure 1, and a plurality of lengths of about 5 m long Directional scaffolding steel single pipe 2a (referred to as "Oyago") is suspended by a chain 10, and the scaffolding steel single pipe 2a is hung in a horizontal state. 2b
(Referred to as “rolling”) is placed, and the intersections thereof are connected to each other via binding metal fittings (not shown), and a safety net (not shown) is provided in a plane including the steel single pipes 2a and 2b for scaffolding. And the scaffold plate 2d is placed on the scaffold steel pipes 2a and 2b. 3 is a morning glory scaffold that is inclined upward to the side of the scaffold 2, and is composed of a large number of steel single pipes (referred to as "location") 3a that are vertically inclined and several horizontally arranged. The steel single pipe (referred to as cloth [nuno]) 3b is combined with the cloth 3b inside in a grid pattern and connected to each other through a binding metal fitting (not shown). A blindfold plate 7 called a control panel is attached with the blindfold fitting 4 of the invention interposed. An enclosing net 8 may be provided on the outer surface of the blindfold as needed.

The details of the blind mounting bracket 4 of the present invention will be described. In the first invention, a cross section is formed by a pair of parallel main wings 5a and sub wings 5b and an intermediate wall 5c connecting the middle of the main wings 5a and sub wings 5b. While forming the H-shaped holding part 5,
The pipe mounting clamp 6 may be attached to the outer surface of the main wing 5a (a bolt (not shown) may be screwed from the holding piece 6a side of the clamp 5 into a screw hole (not shown) provided in the main wing 5a. ), The auxiliary wing 5b is provided with a plurality of screw holes H for screwing bolts toward the inner surface of the main wing 5a. Further, in the second invention, in addition to the configuration of the first invention, as shown in FIG. 4, an eyebolt screwing hole J is provided in the center of the auxiliary wing 5b. In addition, 9,1
0 is an eyebolt and a chain, respectively.

The pipe clamp 6 has two surrounding pieces 6a and 6b having a circular (FIG. 3) or square (FIG. 4) inner edge.
One end is rotatably coupled with a hinge 6c, a bolt 6d is pivotally attached to one of the other ends by a pin 6e, and a nut 6f is screwed to the bolt 6d. Notch 6 to hang bolt 6d on the end of one enclosure piece 6b
With h opened, the cloth 3b can be clamped by sandwiching the cloth 3b between the surrounding pieces 6a and 6b, hooking the bolt 6d on the notch 6h, and tightening the nut 6f.

The operation will be described with reference to the drawings. After horizontally sandwiching the cloth 3b by the sandwiching metal fitting 6 which is a part of the blindfold mounting metal fitting 4, the main wing 5a and the auxiliary wing of the sandwiching portion 5 of the blindfold mounting metal fitting 4 arranged above and below. The upper edge and the lower edge of the blindfold plate 7 are inserted between the blindfold plate 5 and 5b, and the bolts 5h screwed from the side of the auxiliary blade 5b into the plurality of bolt screwing holes H are tightened to fasten the blindfold plate 7 to the holding portion 5. In this way, as shown in FIG. 4, a plurality of blind fittings 4 can be horizontally sandwiched between a plurality of steps of cloth 3b, and a plurality of blind plates 7 can be connected to each other in a front-rear, left-right, and planar shape. If necessary, the eyebolt 9 may be screwed into the screw hole J to fix it, and the chain 1
Sometimes 0 is connected.

In the third invention, as shown in FIGS. 5 and 6, a nail 5e is used instead of the bolt 5h. The fourth invention uses a leaf spring 5f in place of the bolt 5h as shown in FIGS. In the fifth aspect of the invention, as shown in FIGS. 10 and 11, instead of the bolt 5h, a wedge 5k connected to the holding portion 5 by a chain 5j is used.

[0011]

Since the present invention is constructed as described above,
Unlike the conventional morning glory scaffold 3, it is not necessary to tie the rafters with a number line or to nail the blindfold plate 7 to the rafters,
The work becomes easy, and both temporary and temporary removal of scaffolds and blinds can be done in a short time and safely.
